+ARGUMENT:: minFreq
+The minimum frequency that the algorithm will search for an estimated fundamental. This sets the lowest value that will be generated.
+
+ARGUMENT:: maxFreq
+The maximum frequency that the algorithm will search for an estimated fundamental. This sets the highest value that will be generated.
+
+ARGUMENT:: unit
+The unit of the estimated value. The default of 0 is in Hz. A value of 1 will convert to MIDI note values.
+
 ARGUMENT:: windowSize
 	The window size. As sinusoidal estimation relies on spectral frames, we need to decide what precision we give it spectrally and temporally, in line with Gabor Uncertainty principles. http://www.subsurfwiki.org/wiki/Gabor_uncertainty
